中文摘要：

由于当今软件系统的复杂性，模型驱动的软件开发中需要的建模语言和转换定义语言往往是多种多样的．本文阐述了对一个可满足这种需要的元建模平台的研制．其中着重论述了对建模语言的元模型和表示法进行建模的技术，建模语言质量保证机制，以及针对所建立的建模语言和转换定义语言提供自动生成相应工具的设施．

英文摘要：

Because of the complexity of software systems nowadays, the manifold modeling languages and transformation definition languages are needed in model driven software development. This paper presents a meta-modeling platform for defining and improving the needed languages, The paper primarily discusses the technology of modeling meta-models and notations of modeling languages, the mechanism for the assuring modeling language quality, and the facility for automatically generating the related tools aiming at the defined languages.
